针对上面的配置，注意下面两点：
1. log_format如上的配置后，nginx的log日志中就能显示客户端访问的来源ip了。如下：
[root@inner-lb01 ~]# tail -10 /data/nginx/logs/bs7001.wangshibo.cn-access.log

2. nginx的静态缓存配置：
proxy_cache_path /var/www/cache 表示定义缓存存储目录,手动创建；
levels=1:2 缓存级别,表示缓存目录的第一级目录是1个字符，第二级目录是2个字符；
keys_zone=mycache:20m 内核中建立用于缓存缓存数据源数据的空间，查找缓存的时候，先从这个内核空间中找到，缓存数据的源数据，然后再到对应目录中查找缓存；
max_size=2048m 缓存空间最大值；
inactive=60m 缓存的数据，60分钟内没有被访问过就删除
proxy_temp_path /var/www/cache/tmp 表示创建缓存的时候可能生成一些临时文件存放的位置，自动创建
2）vhosts虚拟目录的upstream配置

proxy_cache mycache;
proxy_cache_valid 200 302 1h;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
}
} |
由上面的配置需要注意：
proxy_cache mycache; 表示内存缓存源数据空间名字，nginx.conf文件里已经定义
proxy_cache_valid 200 302 1h; 表示200、302状态的页面资源缓存1小时
proxy_cache_valid 301 1d; 表示301状态的页面资源缓存1天
proxy_cache_valid any 1m; 他缓存1分钟

上面脚本执行后，会提示输入cache的缓存目录，然后选择删除缓存文件的条件（这里我选择"按文件类型删除"），选择了删除html 、htm、js、css、jpg 、gif、 png 、jpeg 、bmp 、flv、 swf 、ico这12中文件格式的缓存文件。
或者直接使用find命令查找缓存目录下的文件，直接将文件全部删除

在本地开发的时候，经常会碰到缓存引起的莫名其妙的问题，最暴力的方式就是清掉浏览器的缓存，或者使用Ctrl + F5，Shift + F5强制刷新页面。有时候按了好几下，缓存还是清不掉，只能暂时禁用浏览器静态资源缓存了，配置如下：location ~.*\.(js|css|html|png|jpg)${ add_header Cache-Control no-cache;
}或者location /js
{ add_header Cache-Control no-cache;
}现在，按F5就行了！ |
